Instabug is a tool that helps mobile app developers understand how users experience their apps, providing crucial performance metrics alongside bug reports. This enables developers to proactively handle smaller issues and ensure a smooth user experience (UX). The Instabug Apdex score measures mobile usability by using various performance and stability metrics, returning a figure from 0 to 1 that represents the proportion of satisfactory user sessions. The widget translates this score into four easy-to-parse buckets—Satisfying, Tolerable, Frustrating, and Crashing—to help interpret what raw Apdex scores mean for UX. By combining UX data with crash reports, Instabug provides meaningful, context-driven troubleshooting, allowing developers to tailor their app's performance according to its needs. The tool integrates seamlessly with Datadog Application Performance Management (APM) and Infrastructure Monitoring, enabling developers to troubleshoot and resolve issues quickly.
